3D printers are coming to the home, undoubtedly. In five years. Or maybe ten. No more than twenty.
Until Canon is selling home models for nearly nothing just so they can lock you into buying their proprietary extruder paste cartridges, your options are limited: the cheapest commercial models, like the “desktop-sized” Objet Alaris 30, are still $40k; and building your own, using the open-source RepRap, takes time and skill.
There’s a new option, though, that splits the difference: MakerBot Industries sells a build-yourself variant of the RepRap (still open-source) for $700, called the CupCake CNC.
The 3D models you make with the CupCake CNC won’t be mistaken for ones that come out of commercial printers, but the pro machines aren’t offered with an optional Frostruder that can squirt icing onto cupcakes in preprogrammed patterns, are they?
